201 Transmission of Zearalenone, Deoxynivalenol and Their Metabolites from Sows to Piglets During Lactation with or without an Algae-Clay-Based Decontaminant

Abstract

Abstract This study evaluated effects of an algae-clay-based mycotoxin decontaminant on levels of zearalenone (ZEN), deoxynivalenol (DON) and their derivatives in the colostrum, milk, and serum of sows, as well as in the serum of weaned piglets after maternal mycotoxin exposure from the last week of gestation to weaning (26 days). To this end, 15 sows split into 3 groups (n = 5/group) were fed diets naturally contaminated with 100 (LoZEN) or 300 (HiZEN) µg/kg ZEN, with or without an algae-clay-based mycotoxin decontaminant in the highly contaminated diet. All diets contained 250 µg/kg DON. Dietary treatments did not influence the performance of the sows and piglets. Only α-ZEL significantly increased in the colostrum of sows fed the HiZEN diet, and this increase was even greater in the colostrum of the sows fed the HiZEN diet supplemented with the test decontaminant. However, no differences in milk mycotoxin concentrations were observed at weaning. The greatest concentrations of ZEN, α-ZEL, and β-ZEL were observed in the serum of sows fed the HiZEN diet. When the HiZEN diet was supplemented with the tested algae-clay-based mycotoxin decontaminant, lconcentrations of ZEN and its metabolites were significantly decreased in the serum of sows. Although all sows were fed the same levels of DON, the serum concentration of de-epoxy-DON increased only in the serum of piglets from the sows fed a diet with the non-supplemented HiZEN diet. In conclusion, the tested algae-clay-based mycotoxin decontaminant can decrease concentrations of ZEN and its metabolites in the serum of sows and the level of de-DON in the serum of piglets.
